Selecting the right joint module is one of the most important decisions in humanoid robot design. Different robot joints require different levels of torque, speed, stiffness, and payload capacity. Using the same actuator throughout the robot often increases weight, reduces efficiency, and limits motion performance. The Honpine HPJM-PRO Series Harmonic Joint Modules provide a complete range of integrated joint actuators for humanoid robots, enabling engineers to optimize every joint from the head to the lower body.

VDI 2862 Revision Sets Harmonic Drive Efficiency Gate for Q3 2026: learn how new ηthermal grades could reshape supplier access, OEM bidding, and delivery planning.

Harmonic drive reducers entering the EU will face new CE-RoHS marking rules from August 1, 2026. Learn the compliance impact on certification, exports, costs, and delivery planning.

Humanoid robots are rapidly transforming industries ranging from manufacturing and healthcare to logistics and public services. At the heart of every robot's movement is the actuator—the component responsible for converting electrical energy into precise mechanical motion. Among the different actuator technologies available today, harmonic rotary actuators have become the preferred solution for humanoid robots due to their compact size, high torque density, exceptional positioning accuracy, and reliable performance.
